Application February 21, 1950, Serial No. 145,334

3 Claims.

This invention relates to a dispenser for powder such, for instance, astooth powder.

Usually in the dispensing of powder such, for instance, as tooth powder,a cap is taken on of a can or container for the powder and the powder ispoured upon the tooth brush with the usual result that some of thepowder is spilled oii the brush and lost or wasted.

One of the objects of this invention is to provide a simple .andinexpensive cap for a container for tooth powder by which apredetermined amount of powder may be used.

Another object of this invention is to provide an arrangement so thatthe tooth powder may be spread upon a brush or some surface by a simplemotion of the hand which is used to hold the powder container.

Another object of this invention is to provide a dispensing device whichwill be'about the same size and shape as the conventional tooth powdercan and have a similar size outlet.

Another object of this invention is to provide a cap which may bemanufactured at about the same low cost as the caps which are presentlyin use.

Another object of this invention is to provide a cap which in normal usewill be retained in position upon the top of the tooth powder can sothat it will not become lost and may also serve as a measuring devicefor the powder which is to be dispensed.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described andparticularly pointed out in the appended claims.

In the accompanying drawings:

Figure l is a perspective View of a cylindrical container with mydispensing device provided at the upper end thereof;

Figure 2 is a sectional View on a somewhat larger scale of thedispensing device showing fragmentally the top portion of the outercontainer;

Figure 3 is a sectional View similar to Figure 2 but showing thedispensing device in open instead of closed position;

Figure 4 is a view of the powder being discharged into the cap prior toshaking the same out of the cap; I

Figure 5 is a sectional view on line 5-5 of Figure 3;

Figure 6 is a perspective view of the two parts of the dispensing orclosure device shown in exploded or separated relation.

7 In proceeding with this invention I provide a dispensing and closuredevice for a powder container composed of two parts which are axiallyslidable and when moved into collapsed position'serve to close thedispensing opening but when moved to open position which is apredetermined position of the two parts, a space is provided into whicha predetermined quantity of powder may be poured and thereafterdischarged through an opening in the outer of the two members.

With reference to the drawings, it designates the powder containerhaving a bottom rolled on as at H and a top wall I2. This top wall l2may have a shallow neck 53 to which the closure and dispensing device isattached.

The closure and dispensing device is designated generally M andcomprises an inner tubular member [5, the lower edge of which is securedto the collar it, while an end wall it closes off the upper end of thistubular member, except for an openin ll which is located at one side ofthe central axis of the tubular side Walls of this member It. The outertubular member is designated generally 18 and comprises a tubular sidewall portion ill of the same shape as the tubular walls of the memberIE, but is slightly larger than the outer diameter thereof so as totelescope over this member is and slide axially thereof. An end wall itcloses this outer tubular member and is enlarged or flanged as at 2iwith a roughened surface so that the same may serve as a handle and beeasily grasped between the fingers. The side wall on part of this flangeis provided with an elongated opening 22 which is located at one side ofthis member l8 and preferably at the side which is diametricallyopposite the axis from the opening ll.

The tubular portions of the members it and I8 are axially slidable andwhen the end walls 26 and it are in engagement, as shown in Figure 2,the opening ll is closed so that no powder may be passed out of thisopening, and in order that these parts may be held in this closedposition, I have provided axially extending ribs 25 extending outwardlyfrom the tubular walls of the member 15 at various locations about itssurface and have provided an inwardly extending circular rib 2% on thewall it so as to engage below the end 21 of the rib 25, while anothercircular rib 28 is provided at a point spaced therefrom to enter a break29 in the rib to provide for doubly securing the parts in their closedtelescopic position.

In order to hold, the parts in an open position, such as shown in Figure3, the outer member [8 may be moved axially upwardly until the rib 26engages the space 29, as shown in Figure 3, and in this position providea predetermined volume 30 between the top walls or end walls I and 20 ofthe two telescoping members, and when in this position powder may bedischarged into the space 30, as shown in Figure 4, and after this spaceis filled, then by positioning the container from an inverted positionto a generally horizontal position, the powder may be dispensed throughthe opening 22. By rolling the can when in this generally horizontalposition, the powder may be nicely discharged through this elongatedopening and spread along the tooth brush or if some other powder is usedfor some other purpose, it may be nicely controlled in this manner.

In some cases a paper washer 33 may be inserted beneath the end wall 20to provide a cushion-like closure or seal.

The closure member 19 may be entirely removed by exerting suflicientpull to slide it over the ribs 25.

I claim:

1. A dispensing closure device for a powder container comprising innerand outer telescoping tubular members slidably related in a directionaxially of the members, both of said members having a tubular wall andend walls spanning the tubular walls in a single plane at right anglestothe axis of the members at the corresponding ends of the members, anopening in the end wall of the inner member at one side of the axialcenter of the members and an opening in the tubular wall of the outermember at the diametrically opposite side of the axial center of themembers, stop means to prevent rotation of the members whereby when theend walls are separated a discharge passage through said openings andbetween said end walls is provided.

2. A dispensing closure device as in claim 1 wherein stop means carriedby said members limit the movement of the end Walls from each other topredetermine a space of a certain volume for measuring the amount ofpowder.

3. A dispensing closure device as in claim 1 wherein interengaging meanscarried by said members hold the end walls of the members in engagementto close the container.
